Listeria can cause serious infection in certain vulnerable groups, resulting in higher rates of hospitalization and death than most other bacteria commonly spread by contaminated food. A new Vital Signs report by the Centers for Disease Control and Prevention outlines the key groups particularly hard hit by Listeria food poisoning. It also highlights the importance of safety measures to prevent contamination of cheese and raw produce, such as those included in the 2011 Food Safety Modernization Act.
